DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following description of the preferred embodiments of the invention is not intended to limit the invention to these preferred embodiments, but rather to enable any person skilled in the art to make and use this invention.

As shown in FIGS. 1A and 1B, the payment terminal 1 includes a secure display 240, a secure input device 230 associated with the secure display 240, a secure processor 210 connected to the secure input device 230, and a main processor 110, distinct from the secure processor 210, which is connected to the secure display 240. The payment terminal 1 functions to provide standard-compliant payment processing (e.g., PCI-complaint payment processing) while enabling access to the merchant-level information. In particular, the payment terminal 1 can function to receive and process payment information in a standard-compliant manner. The payment terminal 1 can additionally function to collect payment information associated with orders or transactions for the merchant. The payment terminal 1 can additionally function as a platform through which third party applications can access and/or process the payment information. The payment terminal 1 can additionally function to automatically determine a type of payment used by a customer, and initiate different consumer payment flows based on the payment type. The payment terminal 1 can additionally function to integrate non-secure payment methods (e.g., cash, payment instruments 50, rewards cards, etc.) into the same payment flow as secured payment methods. The payment terminal 1 can additionally function to interface with peripheral devices, such as legacy payment devices (e.g., pre-existing cash boxes, scanners, etc.), new payment devices, customer traffic trackers, or any other suitable peripheral device. The payment terminal 1 can additionally function to extract information from non-payment instruments, such as drivers licenses, QR codes, or any other suitable information source. Examples of extracted information use include: unique identification of a user for a non-transaction use (e.g., identity verification during voting or by police, loyalty account identification, coupon retrieval or application, etc.), advertising campaign planning, customer purchase prediction, customer traffic prediction, employee performance tracking, employee acquisition planning, automated loan application, automated credit verification, automated settlement, automated accounting, automated or semi-automated tax preparation, automated inventory ordering, automated sale recommendations, or any other suitable transaction-related business functionality.

1. Potential Benefits

This payment terminal 1 can confer several benefits over conventional systems. First, the payment terminal 1 enables application interaction with transaction data generated by conventional payment terminals 600 (e.g., data manipulation) by introducing a main processor 110. Second, the payment terminal 1 can alter the payment terminal user experience by introducing a customer-facing touchscreen display, such that the terminal 1 is no longer a merchant-only device. Introducing a customer-facing touchscreen display can additionally confer the benefit of enabling a dynamically adjustable interface. Third, the payment terminal 1 enables both desktop and mobile use by introducing wireless payment information communication and by forming a handle 310 from its component parts.

2. Auxiliary Systems and Components

The payment terminal 1 can be used with a payment instrument 50 that functions to store financial transaction information that functions as a payment authenticating piece used to carry out a financial transaction. The payment instrument 50 can be a payment card, a token, or any other suitable payment instrument. The payment card can be a credit card, debit card, gift card, fund transfer card, or any other suitable financial transaction card. The token can be a secure element, such as a secure element chip or a virtual element, an integrated circuit (e.g., an IC card, such as an EMV card), or any other suitable token.

The payment terminal 1 can receive, process, and transmit sensitive information and non-sensitive information. Sensitive information can be a set of information required to complete a financial transaction, access a confidential account, or any other suitable information. Examples of sensitive information can include the full payment instrument identifier (e.g., full credit card number), a PIN number, a verification code, a social security number, or any other suitable sensitive information. Non-sensitive information can be any information that is not considered sensitive. Examples of non-sensitive information can include the cart items, the transaction amount, the transaction time, the customer name or other identifier, issuer identifier, last four digits of a payment card identifier, or any other suitable non-sensitive information.

Transmitting information can include sending information, broadcasting information, or otherwise communicating information. Sending information can include passing the information to a limited, predetermined set of endpoints (e.g., a single endpoint) in a targeted manner (e.g., through a targeted distribution channel), wherein endpoints outside of the predetermined set do not receive the information. Broadcasting information can include sending the information or an event associated with the information to multiple endpoints (e.g., all endpoints) through a common distribution channel, such as by putting the information on a common bus. Any endpoint connected to the common distribution channel can subsequently receive and/or the information from the source. However, information can be otherwise transmitted from sources to endpoints.

The payment terminal 1 can function to generate or otherwise process order information. Order information can include transaction information, cart or product information (e.g., product identifier, number of each product, etc.), customer identifiers, merchant identifiers, employee identifiers, order status (e.g., completed, open, paid but not picked up, etc.), or any other suitable order information. Transaction information can include a transaction identifier, transaction amount, merchant information, customer identifier, payment type, terminal identifier, and/or any other suitable information about the transaction. The transaction identifier can be universally unique, unique to the merchant, unique to the customer identifier, generic, or be defined in any other suitable manner.

The payment terminal 1 can interact with a payment verification system (payment entity) that functions to verify payments or otherwise facilitate payment verification. The payment verification system can be the payment instrument 50 (e.g., the IC chip or secure element), a payment gateway, a payment processor, a financial service provider (e.g., a credit card provider, bank, etc.), or be any other suitable entity or system capable of verifying or facilitating verification of a payment.

As shown in FIG. 7, the payment terminal 1 can interact with a remote system 40 which functions to store merchant information. The remote system can additionally or alternatively function to facilitate payment verification, wherein the remote system can send secured payment information to the payment verification system. The secured payment information can be received from the payment terminal 1, or be automatically generated by the remote system. The merchant information can be sensitive information, non-sensitive information, or a combination thereof. The merchant information can include order information, transaction information, customer information, merchant account information, user account information for users associated with the merchant (e.g., employee accounts), permissions for user application access, permissions for application information access, permissions for order information access (e.g., authorization, authentication, etc.), terminal activation control, or any other suitable merchant information. The remote system can be a remote computing system or be any other suitable system. The payment terminal 1 can be connected to the remote system through a wired connection (e.g., LAN, cable, etc.) or wireless connection (e.g., WiFi, cellular, Bluetooth, etc.).

The payment terminal 1 can function to secure information. Securing information can include obfuscating information, encrypting information (e.g., using symmetric key encryption, public key encryption, etc.), or otherwise securing the information.

3. Payment Terminal Components and Variations

As shown in FIG. 8, the secure display 240 (customer display, first display) of the payment terminal 1 functions to display order information, user interface elements, targets, windows for user input receipt, or any other suitable image to a user. In some variations of the payment terminal 1 (e.g., those with a single display), the secure display 240 can additionally function as the merchant display, wherein the processor controlling secure display operation (e.g., the main processor 110) can dynamically shift secure display control between a first and second distinct kernel, switch operation modes between a secured and unsecured mode, or otherwise shift control of the secure display 240 based on user selections (e.g., a payment initiation selection) and/or information received at the secure processor 210 (e.g., payment instrument detection). The secure display 240 can be an LCD display, LED display, plasma display, OLED display, or any other suitable display. The secure display 240 can define a broad face having a longitudinal axis and lateral axis. The secure display 240 can be planar, curved, or have any other suitable broad face configuration. The secure display 240 can be substantially rectangular (e.g., square or with a length longer than a width), triangular, circular, or have any other suitable profile. The secure display 240 is preferably controlled by the main processor 110, but can alternatively be controlled by a processor that is separate and distinct from the main processor no. The secure display 240 is preferably controlled by a secure display resource of the main processor no, but can alternatively be controlled by a payment resource or any other suitable resource of the main processor no. In a specific example, the secure display 240 can only be controlled by the main processor no. However, the secure display 240 can be controlled by any other suitable component. The secure display 240 can be connected to the main processor no by a wired connection, such as a display cable, display bus, male/female connection (e.g., PCI express, etc.), MIPI, or any other suitable wired connection, or a wireless connection, such as Bluetooth, BLE, NFC, or any other suitable wireless communication system.

The secure input device 230 (customer input device, secure input, first input device) of the payment terminal 1 functions to receive a user input and convert the user input into input signals 231 (e.g., measurements) indicative of the user input. In some variations of the payment terminal 1 (e.g., those with a single display or input device), the secure input device 230 can additionally function as the merchant input device, wherein the processor controlling secure display operation (e.g., the secure input processor 220) can dynamically switch operation modes or otherwise shift operation based on user selections (e.g., a payment initiation selection) and/or information received at the secure processor 210 (e.g., payment instrument detection).

The secure input device 230 is preferably associated with the secure display 240, wherein the user input measurements generated by the secure input device 230 are translated into selection information based on the actual or anticipated image or interface (display element 242) concurrently displayed on the secure display 240 during measurement receipt. However, the secure input device 230 can be associated with any other suitable display.

The secure input device 230 is preferably connected to the secure processing system 200, more preferably the secure input processor 220 but alternatively the secure processor 210 or any other suitable processor. Alternatively or additionally, the secure input device 230 can be connected to the main processor 110, main input processor 140, or any other suitable processor. The secure input device 230 preferably only sends the measurements or other signals to the connected processor, but can alternatively or additionally send the measurements to any other suitable endpoint. The secure input device 230 can additionally be controlled by the connected processor, wherein the connected processor can control power provision to the secure input device 230, control or instruct the secure input device 230 to introduce signal noise into the measurement, or control or instruct the secure input device 230 to operate in any other suitable manner. The secure input device 230 can receive power directly from a power source 600, such as a charging port 630 or a power storage unit (e.g., battery), receive power indirectly from the power source 600 through the connected processor, or be powered in any suitable manner. The secure input device 230 can be connected to the secure processor 210 by a wired connection, such as a cable, bus, male/female connection, MIPI, or any other suitable wired connection, or a wireless connection, such as Bluetooth, BLE, NFC, or any other suitable wireless communication system.

The secure input device 230 is preferably operable in a single mode (e.g., a secured mode), but can alternatively operate between a secured mode and an unsecured mode, or between any other suitable set of modes. In the secured mode, the secure input device 230 can secure (e.g., obfuscate) the measurements sent to the secure input processor 220, secure processor 210, other component of the secure processing system 200, main processor 110, or any other suitable destination. In the unsecured mode, the secure input device 230 can send unsecured measurements to the secure input processor 220, secure processor 210, other component of the secure processing system 200, main processor 110, or any other suitable destination. The secure input device operation mode can be controlled by the secure input processor 220, a separate and distinct processor or driver, or by any other suitable control system. The secure input device operation mode can be the same as (e.g., reflect) the connected processor operation mode, or can be independent of the connected processor operation mode.

The secure input device 230 can be a touchscreen 232, a pointing device, a keyboard, a sound input (e.g., a microphone), or any other suitable input device. The secure touchscreen can function to enable a user to interact directly with what is displayed on the secure display 240. The pointing device, keyboard, or other input devices can enable the user to interact indirectly with what is displayed on the secure display 240. The secure touchscreen is preferably overlaid over the secure display 240, such that touch coordinates registered by the secure touchscreen can be mapped to pixel sets, digital interaction elements, or other virtual targets displayed on the secure display 240. The secure touchscreen preferably has substantially the same dimensions as the secure display 240, but can alternatively be larger (e.g., extend over all or a portion of the display bezel) or smaller. The secure touchscreen preferably has a similar pixel density as the secure display 240, but can alternatively be denser (e.g., 3 times denser) or sparser. The secure touchscreen is preferably substantially aligned with the secure display 240, such that the touchscreen longitudinal axis and lateral axis are substantially aligned with the secure display 240 longitudinal axis and lateral axis. However, the secure touchscreen can be misaligned with the secure display 240 (e.g., with an offset central normal axis), or aligned in any other suitable orientation. The secure touchscreen can include a broad face, wherein the secure touchscreen broad face is substantially parallel the secure display broad face. Alternatively, the secure touchscreen can be arranged in any suitable configuration relative to the broad face.

The touchscreen can be a resistive touchscreen, surface acoustic wave touchscreen, capacitive touchscreen, infrared grid touchscreen, infrared acrylic projection touchscreen, optical imaging touchscreen, dispersive signal technology touchscreen, acoustic pulse recognition touchscreen, or utilize any other suitable touchscreen technology. Examples of capacitive touchscreens include a surface capacitance touchscreen, projected capacitance touchscreen, such as mutual capacitance touchscreen or self-capacitance touchscreen, or any other suitable capacitive touchscreen. In a specific example, the touchscreen is a PIN transaction security (PTS)-compliant and/or PIN encryption device (PED)-compliant touchscreen. The measurements or signals output by the touchscreen are preferably touch measurements, and can include the capacitance change for each of a plurality of touchscreen points, capacitor, or any other suitable measurement location. However, the measurements or signals can be determined from the position of a switch, a potential voltage magnitude, a change in the voltage magnitude, the current magnitude, the current frequency, or from any other suitable signal.

The touchscreen can include one or more layers. In one variation, the touchscreen includes a translucent top layer including a metallic coating along a first surface, an adhesive spacer proximal the first surface, a translucent bottom layer including metallic coating along a second surface proximal the first surface, and a translucent mounting layer. The touchscreen is preferably substantially transparent, but can alternatively have any other suitable translucidity. The top and bottom layers can be formed from the same materials or different materials. The top and/or bottom layers can be formed from polymer (e.g., polyester, PEG, etc.), glass, or any other suitable substrate material. The touchscreen can additionally include a polarizing filter that functions to limit the viewing angle, coupled along a second surface of the top layer opposing the first surface, the first surface of the top layer, the first or second surface of the bottom layer, along the broad face of the display proximal the touchscreen, or along any other suitable surface. The touchscreen can include a first broad face extending over the respective display broad face, more preferably proximal the display active surface but alternatively along any other suitable portion of the display.

The secure processor 210 of the payment terminal 1 functions to perform a predefined set of functionalities. The secure processor 210 can additionally function to determine whether received information includes sensitive information, separate the sensitive information from non-sensitive information, secure sensitive information, or otherwise process received information. Application interaction (e.g., reading, writing, editing, and/or deletion) from all or some of the memory and processes connected to or supported by the secure processor 210 is preferably limited to a predetermined set of main processor modules (e.g., standard-certified or compliant modules, such as the payment module), but can alternatively be entirely prevented or otherwise limited. The secure processor 210 can be dynamically updated (e.g., wherein the secure processor 210 receives encrypted update information from the main processor 110) or be otherwise adjusted in any other suitable manner. The secure processor 210 is preferably separate (e.g., forming or viewed as a unit apart or by itself) and distinct (e.g., recognizably different in nature) from the main processor no, but can alternatively be separate from the main processor 110, distinct from the main processor no, be a portion (e.g., a core) of the main processor no, be a sub-processing module of a processor that also supports the main processor no, or have any other suitable relation to the main processor no. The secure processor 210 can be supported on a different chipset, different circuit board, different core, different kernel, different thread, or otherwise separated and/or distinguished from the main processor no. The secure processor 210 can be standard-compliant, standard-certified, standard-signed, otherwise compliant with a payment industry security standard, or be non-compliant with industry standards. Examples of a payment card industry standard includes PCI DSS (Payment Card Industry Data Security Standard), PCI P2PE, PTS, or EMVCo, but any other suitable payment industry security standard can be used. The secure processor 210 can include or be associated with secure memory (e.g., volatile memory, non-volatile memory, etc.), wherein the secure memory can be separate and distinct, integrated with, or be the same as the main memory. The secure memory can store encryption keys, coordinate maps (e.g., for input coordinate interpretation when the terminal is in the secured mode), firmware, certificates, or any other suitable information. The secure memory can be read only, write only, read/write, or have any other suitable functionality.

The secure processor 210 can be connected to the secure input device 230, wherein the secure processor 210 can receive information from the secure input device 230. In one variation, the secure processor 210 can be indirectly connected to the secure input device 230 through an intermediary processor, such as a secure input processor 220 (e.g., secure touch processor). In this variation, the received information can include a set of input coordinates (e.g., touch coordinates, selection coordinates). The set of input coordinates can be determined from the measurements (e.g., input signals) by the intermediary processor, or otherwise determined. The set of input coordinates can be secured or unsecured (e.g., by the intermediary processor or secure input device 230). However, the received information can additionally or alternatively include any other suitable information. In this variation, the secure processor 210 can be selectively operatively connected to the secure input device 230 by the intermediary processor or continuously operatively connected to the secure input device 230 by the intermediary processor. The secure processor 210 can receive secure input device information (e.g., input signals, input coordinates, etc.) from the intermediary processor when operatively connected to the secure input device 230, and cannot receive secure input device information from the intermediary processor when not operatively connected to the secure input device 230. The secure processor 210 can be prevented from receiving secure input device information when not operatively connected to the secure input device 230, or simply not sent secure input device information by the intermediary processor. The secure processor 210 can be virtually prevented from receiving the secure input device information, such as by implementing a firewall or virtually disconnecting the secure processor 210 from the secure input device 230, physically prevented from receiving the secure input device information, such as by disconnecting the secure processor 210 from the secure input device 230 (e.g., by changing the state of a switch), or otherwise prevented from receiving secure input device information.

In a second variation, the secure processor 210 can be directly connected to the secure input device 230. In this variation, the received information can include all or a portion of the measurements from the secure input device 230. However, the secure processor 210 can be otherwise connected to and receive information from the secure input device 230.

The secure processor 210 can additionally be connected to the payment hardware 250. The secure processor 210 can be directly connected to the payment hardware 250, indirectly connected to the payment hardware 250 (e.g., through a secure financial information processor, in a similar manner to indirect secure processor connection with the secure input device 230, as discussed above), or otherwise connected to the payment hardware 250. When the terminal 1 includes a secure financial transaction processor, the secure financial information processor can receive information (e.g., payment instrument data or information, identification information, etc.) from the payment hardware 250, determine whether the information is sensitive, and send the information to the secure processor 210 in response to the financial information being sensitive information, and to the main processor 110 in response to the financial information being non-sensitive information. Alternatively, these functionalities can be performed by the secure processor. The secure financial transaction processor can be operable only in the secured mode, or can be operable between a secured mode and an unsecured mode, or operate between any suitable set of operation modes. However, the secure financial transaction processor can operate in any other suitable manner. The secure financial transaction processor can be separate and/or distinct from the secure processor 210, integrated with the secure processor 210, integrated with the main processor 110, or otherwise configured.

The secure processor 210 can be operatively connected to the payment hardware 250, or be otherwise connected. When the secure processor 210 is operatively connected to the payment hardware 250, the secure processor 210 can receive all or a portion of the information determined by the payment hardware 250. The secure processor 210 can additionally or alternatively control payment hardware operation when operatively connected to the payment hardware 250. The secure processor 210 is preferably continuously operatively connected to the payment hardware 250, but can alternatively be selectively operatively connected to the payment hardware 250 (e.g., by an intermediary payment hardware 250 processor), only connected to the payment hardware 250 by a power connection, or otherwise connected to the payment hardware 250.

The secure processor 210 can additionally be connected to the main processor no. The secure processor 210 can be directly connected to the main processor no, indirectly connected to the main processor no (e.g., in a similar manner to indirect secure processor connection with the secure input device 230, as discussed above), or otherwise connected to the main processor no. The secure processor 210 can be operatively connected to the main processor no, or be otherwise connected. When the secure processor 210 is operatively connected to the main processor no, the secure processor 210 can only send information 202 (e.g., data) to the main processor no. Alternatively, the secure processor 210 can only receive information from the main processor 110 when operatively connected. Alternatively, the secure processor 210 can both send and receive information to and from the main processor no when operatively connected. Alternatively, the secure processor 210 can be limited to only receiving information from the main processor no when operatively connected to the main processor no. The secure processor 210 is preferably continuously operatively connected to the main processor 110, but can alternatively be selectively operatively connected to the main processor 110, only connected to the main processor 110 by a power connection, or otherwise connected to the main processor 110.

The secure processor 210 is preferably connected to the main processor 110 by a single connection 800, but can alternatively be connected to the main processor 110 by multiple connections. The connection 800 preferably includes both power and data connections, but can alternatively only include a power or data connection. The connection can be a two-way connection (e.g., send data to and from both endpoints), or be a one-way connection (single-direction connection, e.g., only transmit data in one direction from a source to a destination), or be any other suitable type of connection. The connection 800 is preferably a physical connection, such as a wire, bus, or board-to-board connection, but can alternatively be a wireless connection, such as a short-range data connection (e.g., NFC, Bluetooth, BLE, RF, IR, etc.) or long-range data connection (e.g., WiFi, Zigbee, Z-wave, etc.), or be any other suitable connection. In a specific example, the connection can be a USB connector, FireWire connector, or any other suitable wired connector. The connection 800 can additionally include a hardware security module, be formed from optical fiber, be configured to sever in response to physical tampering, or be secured in any other suitable manner. In one variation of the payment terminal 1, the secure processor 210 only outputs information to the main processor 110, and otherwise only received inputs from other terminal components. In a second variation of the payment terminal 1, the secure processor 210 can output information (e.g., control information, etc.) to other terminal components. The connector preferably extends across the junction, but can alternatively extend along any other suitable portion of the terminal 1.

The secure processor 210 preferably operates in a single mode, more preferably the secured mode, but can alternatively operate between a secured mode and an unsecured mode, or between any other suitable set of modes. In the secured mode, the secure processor 210 can secure (e.g., encrypt, obfuscate, etc.) all information output by the secure processor 210 (output information), a subset of the output information (e.g., only information determined to be secure information, such as information satisfying a condition indicative of sensitive information, etc.), or any other suitable portion of the output information. In the unsecured mode, the secure processor 210 can output (e.g., send, transmit, broadcast, etc.) unsecured output information. When the secure processor 210 is operable between a set of operation modes, the secure processor operation mode is preferably controlled by the secure processor 210 but can alternatively be controlled by the main processor 110 or by any other suitable control system.

The secure processor 210 is preferably arranged proximal the secure display 240, but can alternatively be arranged proximal the main display 120, proximal the secure input device 230, proximal the main input device 160, or arranged in any other suitable location. The secure processor 210 is preferably arranged with a broad face substantially parallel the respective display broad face, but can alternatively be arranged in any suitable orientation. The secure processor 210 can be substantially centered with the respective display, offset from the respective display, be arranged proximal an end of the respective display (e.g., along the display longitudinal axis), or otherwise arranged.

The secure input processor 220 (first input processor) of the payment terminal 1 functions to interpret measurements determined at the secure input device 230 into secure reference coordinates. The reference coordinates 221 can be input coordinates (e.g., touchscreen coordinates), display coordinates, or any other suitable reference point that can subsequently be used to determine a user selection with reference to the image or interface concurrently displayed on the secure display 240 during measurement registration. In a specific example, the user selection can be determined based on a coordinate map 244 associated with the concurrently displayed image or interface, as shown in FIG. 9. However, the user selection can be determined in any other suitable manner. The secure input processor 220 can be connected to the secure input device 230, wherein the secure input processor 220 can receive information from the secure input device 230 only (e.g., through a one-way connection), both send and receive information to and from the secure input device 230 (e.g., control information, etc. through a two-way connection), send information to the secure input device 230 only, or be otherwise operatively connected to the secure input device 230. The secure input processor 220 can be connected to the secure input device 230 by a wired connection, such as a cable, bus, male/female connection, or any other suitable wired connection, or a wireless connection, such as Bluetooth, BLE, NFC, or any other suitable wireless communication system. The secure input processor 220 can be can be standard-compliant, standard-certified, standard-signed, otherwise compliant with a payment industry security standard, or be non-compliant with industry standards.

In one variation, the secure input processor 220 is a secure touch processor that functions to convert touch signals (e.g., changes in capacitance) to the reference coordinates 221. In another variation, the secure input processor 220 is a secure device processor that functions to determine a virtual pointer position relative to the image concurrently displayed on the secure display 240. However, the secure input processor 220 can be any other suitable input processor.

The secure input processor 220 can additionally function to secure the reference coordinates 221, or any other suitable information output by the secure input processor 220. The secure input processor 220 can secure all information output by the secure input processor 220, secure output information only when operating in the secure mode, or secure information based on any other suitable operation parameter.

The secure input processor 220 can additionally function to selectively determine the endpoint for the reference coordinates 221. The secure input processor 220 is preferably operable between a secured and an unsecured mode, but can alternatively be operable only in the secured mode, in the unsecured mode, or between any suitable set of operation modes. The secure input processor operation mode is preferably independent of the secure processor 210 (e.g., even when the secure input processor 220 is an integral module of the secure processor 210), but can alternatively be the same as the secure processor operation mode. The secure input processor operation mode is preferably determined (and/or controlled) by the secure input processor itself, but can alternatively be determined by the secure processor 210, the main processor 110, or any other suitable component.

The gap of the printer 500 is oriented to be substantially parallel with the distal secure display end. The gap includes toothed separation mechanisms 560 along both longitudinal edges of the gap. The printer door 540 is arranged distal the secure display back surface, with the hinge 580 distal the distal secure display end, such that the printer door 540 opens away from the secure display 240. The housing 300 preferably traces the surfaces of the printer body 510, remainder of the secure display back face, and main display 120 to cooperatively form a handle 310. The weight of the printer 500 preferably counterbalances the weight of the power source 600. A first contact surface 340 is defined along the distal main display end) and a second contact surface 340 is defined along a longitudinal, arcuate surface of the printer 500 (e.g., along the printer body 510 or the printer door 540). A first camera is arranged along the side of the secure display 240, proximal the distal secure display end, and is oriented with the camera active surface normal vector substantially perpendicular the second contact surface normal vector (e.g., perpendicular a gravity vector). The payment terminal 1 can additionally include a power and data connector arranged between the processor and power source 600, along a longitudinal side of the main display 120. The payment terminal 1 can additionally include a set of docking connectors arranged along an arcuate surface of the printer body 510, configured to connect to an external dock. The power and data connector and docking connectors are connected to the power source 600. The payment terminal 1 can additionally include a WiFi transceiver configured to communicate with a remote device, an NFC transceiver, a Bluetooth transceiver, a beacon transceiver, or any other suitable communication mechanism. The short-range communication modules (e.g., NFC, Bluetooth, beacon, etc.) that function as payment hardware are connected to the secure processor 210. The long-range communication modules are connected to the main processor 110.

In a second example, the payment terminal 1 includes a single display (secure display 240) and a single input device (secure input device 230), a main processor 110, a secure processor 210, a secure input processor 220, a power source 600, and a set of payment hardware 250 (e.g., short-range communication modules, card reader, etc.). The single input device is only connected to and sends information to the secure input processor 220. The secure input processor 220 is connected to and sends information to the main processor 110 and the secure processor 210. The main processor 110 is connected to the secure input processor 220, the power source 600, and the display. The secure processor 210 is only connected to the power source 600, the payment hardware 250, the main processor 110, and the secure input processor 220. The secure processor 210 is connected to the main processor no by a power and data cable. The secure input processor 220 is operable between a secured mode, wherein information is sent to the secure processor 210, and an unsecured mode, wherein information is sent to the main processor 110. The secure input processor 220 switches between the secured and unsecured mode in response to a switching event. The switch event can be the initiation of a payment flow (e.g., in response to selection of a “charge” icon), the receipt of financial transaction information from the payment hardware 250, the detected position of the payment terminal 1, or any other suitable event. In a first specific example, the payment terminal 1 can operate in the unsecured mode in response to the accelerometer indicating a first terminal orientation, and in a secured mode in response to the accelerometer indicating a second terminal orientation (e.g., opposing the first orientation). In a second specific example, the payment terminal 1 can operate in the unsecured mode in response to a switch operating in a first position, and in the secured mode in response to the switch operating in a second position. The switch is preferably switched from the first to the second position when the terminal 1 is rotated about a rotational axis substantially normal to a terminal contact surface 340.
